How do I project in split screen mode?

• You can use the Split Screen feature to simultaneously project two images from different video sources next to each other. You can control the Split Screen feature using the remote control or the projector menus. See Projecting in Split Screen mode for instructions.
  
  The Split Screen feature is only available with certain combinations of video sources. Use the table below to determine which video source combinations are available.
  
  Note: When you use the Split Screen feature, other projector features may not be available and some settings may be automatically applied to both images. You also cant access Split Screen mode when USB is the active display source or 3D mode is enabled.
